Excellent disc! If I could, I would like to request some additional patterns for consideration please:

a) please add a 75% white to the Color Patterns for both Rec 709 and 601 (so we have r,g,b,y,c,m and now White too). My software package prompts me to measure white in addition to the primaries and secondaries, and without this I do not have a 75% white anywhere else on the disc to use (and it needs to match the 75% of the other colors).

b) please consider making the color patterns also available at 100%

c) please add a set of IRE windows that go by 5 IREs (5, 10, 15 etc). Or if not then please add a single 5 IRE window. I can measure accurately at 5 IRE and like to dial that in.

d) please consider adding a pattern that consists of 6 horizontal bars from 0 to 10 IRE (0, 2, 4, 6, 8, 10) as this helps give a good idea of how things hold up in the low end.

Thank you!

Sure, those are all very easy. On the 6 bar low IRE pattern, "horizontal" is a little ambiguous. Do you want this:

or this:

Hi Ron - regarding the 6 step 0-10 IRE pattern - originally I was thinking the 2nd one. However after seeing this it is obviously that going with the first one (top image) would be much better because the bars are "thicker" and will be easier to judge color shifts/differences as a result. This is also more consistent with the orientation of most IRE bar patterns. So in summary, please use the style as shown in your top (first) image. Thanks!

Ron great work!! I would love to see some AVIA style color bars with the flashing boxes. The flashing boxes make it a ton easier to get your adjusts just right. Is this doable?

Actually, I brightened those images a little so that all the bars could be easily seen. Here's the pattern at the proper levels.



I'm wondering if a 0 to 20 IRE pattern (also at proper levels) would be better?

Flashing is easy. I'll have to find my Avia disc to remember what the patterns look like.

Hi Ron -

I haven't checked them all but, is one of these a 24p moving vertical chroma (only) resolution test pattern? It would be interesting to see if the different blue laser DVD players have more or less vertical chroma rez due to a pass through 1080i processing.

That is a good idea, I find that the flashing colorbar boxes aid with precision.

That's great! I find the AVIA patterns are easier to use than DVE. You can find a nice screen shot of the color bars with flashing squares here: zapped by jr poster policy

The 360 needs a different chapter marking setup.

There is a different thread with instructions and a download for a 360 friendly disc.

sorry, calibration newby.

is there a thread that explains what they do/how to use all these test streams?

I have the hd-dvd up and running and also all the files on my PS3. I own Avia and have used it serveral times

thanks

Has anyone tried transferring the .ts files to their Tivo(HR10-250 or Series 3)? I would think a .ts file is a .ts file, but wanted to make sure before going through the hassle of getting into my tivo. I'd like to have these come from the "source" to adjust for any discrepencies.
thanks

How can you get a .ts file into a S3? That would be very nice to get these loaded there.

I don't know, I thought they were as open as the series 2's. I have the D* version. I was just specifying an HD tivo not SD. Sorry about the confusion...

edit, nevermind, I'd have to convert it to a .ty file....

Nope. They are closed tight as a.... Well, they have them locked down tight. You can't even use the SATA port that's built in, or any of the Tivo sharing between boxes stuff. Just hoped you had heard some hack to do it. I haven't had time to watch for one.

That does bring up an interesting idea though. Not to get OT but if one had a Sencore ATSc generator for a couple hours you could record the patterns via the Antenna port. That woudl be cool. Anyone have a Sencore HD I can borrow

I've recently loaded some of these .ts files onto my HR10-250.

Basic process is convert .ts to .mpg via HDTVtoMPEG2 and then to .ty via FFMPEG. Resulting .ty file is then put onto HR10-250 via MFS_FTP. Of couse, all this assumes you have a hacked tivo with network access.

Files play fine, and although I've not yet done any calibration with these files, they seem to be intact.

Thanks,
I've converted the .ts to .ty using tyffmpeg, but I need to work out the insertion using MFS_FTP. I'm new to all of this stuff.

edit, After converting, did your files shrink? I asked on elsewhere, but I used the -acodec copy and -vcodec copy flags in ffmpeg and the irewindows went from 70Mb to 7Mb...

* disclaimer, I am not trying to take anything off the tivo....

Yes they did shrink. Converting to MPG in HDTVtoMPEG2 reduced the file sizes. Not sure why. For example Bars709 went from 70,102KB down to 7,085KB. It was further reduced to 6,402KB after running through FFMPEG. I know that these files zip well as they are very redundant, maybe that has something to do with the decrease in file size. Don't know if their quality was reduced.

The true test is to convert back the other way (when possible) and see if there were losses on the resulting images.

I am pretty sure the TS are packed with NULL packets to fill them out to 19.2Mbps. HDTVtoMPEG2 removes them thus the file size shrinkage. Most of the clips are non moving patterns so actual data rate should be very small.

yeah bars709 is 90.2% NULL packets. I use TSReader lite to look out what is in the transport stream, cool program
